NullPointerException error

[glv]

Hello @onosecond ,

It also helps to share where you are getting the errors:

This is usually highlighted.

In this case there are two messages in the console:

• The image was missing.
• It generated a NullPointerException when trying to display it.

You must then interpret the messages and try to resolve what is causing the issue.

Note that if you post extra code, you might be asked to narrow your problem down to a Minimum, Complete, Verifiable Example . This just means that you should try to isolate your code into a smaller example.
